half way thru a yard last night the middle spindle began smoking, initially i thought it was just some grass up around the pulley. i shut down the blades, pulled up the trailer to check the underside. it all looked good under there and everything was free spinning. well i continued to finish cutting the yard without another waft of smoke. once i got back to my shop and pulled in i noticed there were some metal shavings under the pulley. what do you guys think is the bearing smoked or something bigger?? even if its the spindle and the bearing how easy is it to fix without paying a shop a ton of money to do it. i am fairly mechanical i'm just new to this brand and unsure of where to get the parts i need. it would be greatly appreciated if you guys could point me in a good direction.
